The Class D51 (D51形) is a type of 2-8-2 steam locomotive built by the Japanese Government Railways (JGR), the Japanese National Railways (JNR), and Kawasaki Heavy Industries Rolling Stock Company, Kisha Seizo, Hitachi, Nippon Sharyo, Mitsubishi, and Mitsubishi Heavy Industries from 1936 to 1945 and 1950 to 1951. 174 units are in preservation in Japan, including five operational examples. A further 13 are preserved in Russia and Taiwan, bringing the total number of preserved units to 187.

Design and operation

[edit]

The design of class D51 was based on the earlier D50, introduced in 1923. Wartime production featured some substitution of wood for steel parts like running boards, smoke deflectors and tender coal bunkers. A total of 1,115 D51s were built,[2] the largest number in any single class of locomotive in Japan. Early D51s were nicknamed Namekuji-gata ("slug-form") for their shape. The locomotive was designed by Hideo Shima. It was used mainly in freight service through the 1960s. Some D51s were fitted with the Giesl ejector in Hokkaido to conserve on fuel.[3]

Service outside Japan

[edit]

Soviet Railways D51

[edit]

The 30 specially built D51s that were left on Sakhalin (formerly Karafuto) by the retreating Japanese at the end of the Second Sino-Japanese War (1937-1945) and after the Soviet-Japanese War (1945), were used from 1945 until 1979 by Soviet Railways. One was left outside Yuzhno-Sakhalinsk railway station, and one is in running condition and is kept at the Yuzhno-Sakhalinsk railway station. Additionally two wrecks were left to the north of the city.[4]

Korean National Railways Mika7

[edit]

Two locomotives were built for the Korean National Railroad in 1950 by Mitsubishi for South Korea during the Korean War. Designated Mika7 (미카7) class, they were nearly identical to JNR class D51 except for the gauge.[5]

Manila Railroad 300 class (1951)

[edit]

According to the a journal published in 1956, ten locomotives were built by Nippon Sharyo for the Manila Railroad Company. These entered service in 1951. Numbered the 300 class, they were named after the cog locomotive class built in the 1910s for the Manila Railway. These locomotives differed from the rest of the D51 builds through the lack of smoke deflectors.[6]

The locomotives had a short service life in the Philippines as Manila Railroad ordered the dieselization of its entire network, having all steam locomotives retired by 1956.[7]

Taiwan Railways Administration DT650

[edit]

From 1936 to 1944, Kawasaki, Kisha Seizō and Hitachi had built 32 D51s for Imperial Taiwan Railway. After World War II, they were taken over by Taiwan Railways Administration, and were classified DT650. In 1951, Kisha Seizō built three DT650s and Mitsubishi Heavy Industries built two DT650s for Taiwan Railways Administration.[8]

Classification

[edit]
Main article: Japan Railways locomotive numbering and classification

The classification consists of a "D" for the four sets of driving wheels and the class number 51 for tender locomotives that the numbers 50 through 99 were assigned to under the 1928 locomotive classification rule.

Preserved examples

[edit]

Over 173 Class D51 locomotives are preserved in Japan. D51 498 was restored by JR East and pulls special-event trains on JR East lines.[9]
